2 Claims.

'Ihe invention aims to provide a new and improved brooder or the like in which novel provision is made for maintaining the living quarters at proper temperature without admitting thereto any air which has come in contact with a heater and has therefore had its oxygen content impaired. By a novel arrangement of chambers and flues, the air heated by the heater is circulated under and at the sides of the chick room Without entering the latter, and said room is provided with a fresh air inlet and an outlet for foul air and moisture.

With the above object in view, the invention resides in the novel subject matter hereinafter described and claimed, description being accom-` plished by reference to the accompanying drawings.

Fig. 1 is a side elevation partlyA broken away. Fig. 2 is a vertical transverse section on line 20 2 2 0f Fig. 1.

Fig. 3 is a fragmentary horizontal line 3-3 of Fig. 1.

Fig. 4 is a fragmentary sectional perspective View showing the relation of one of the downdraught flues with the horizontal and vertical air chambers.

In the drawings above briey described, C denotes an inner casing whose interior constitutes .a room for the chicks. The bottom of this casing is denoted at 5 and the surrounding vertical wall at 6. A woven wire floor 1 has been shown supported above the bottom 5 upon suitable supports 8, and a pan 9 for droppings is removably supported under said bottom 'I upon angle iron supports I0.

An outer or jacket casing O is provided with a bottom I I spaced downwardly from the bottom 5 of the inner casing C to provide a horizontal air chamber A, the surrounding wall I2 of said casing O being spaced outwardly from the wall 6 of the casing C to provide a Vertical air chamber A', the two chambers A and A' being in communication with each other. l l

A coal-oil heater H or heater of other suitable type is provided to heat the air in the chamber A, and down-draught iiues I 3 extend from the upper portion of the air chamber A' to the chamber A to cause the air heated in said chamber A to ascend into said chamber A and then descend section on (through the flues I3) for re-heating.`

ilues An intermediate wall I4 is preferably located between the walls 6 and I2, the space between two walls I2 and I4 being lled with thermal packing I5 for insulating purposes. The down-draught I3 are also located between the walls I2 and I4, the upper ends of said flues being in communication with openings I6 formed through the wall Y I4, while the lower ends of said flues communicate with openings I 1 formed through said Wall I4. Each flue I3 is preferably bent from sheet metal into'channel shape and is provided with attach' ing flanges I8 suitably secured to vthe intermediate wall I4.

The inner and outer casings are preferably formed from suitable gauge-sheet metal appropriately secured to a suitable wooden framework. 'I'he same is true of the'top or roof I9, which top or roof is of insulated construction and may well embody a pair of upwardly swingable sections 20 mounted on appropriate hingesZI.. Other doors or the like 22, 23 may be provided Where desired, the door 23 being positioned to allow Withdrawal and reinsertion of the pan 9.

Underthe outer casing bottom II is a suitable casing or enclosure 24 for the heater H to prevent waste of the heat radiating therefrom. In the present showing, an oil tank 25 is provided for the burner of the heater H, and the oil line 26 to said burner from sand tank preferably extends between the Walls 6 and I4 for a portion of its length. This oil line includes an appropriate regulating valve 2'I controlled by a thermostat 28 Within the chick room. A suitable smoke outlet 29 leads from the heater H'to` carry off smoke and fumes. l

A fresh air inlet 30 is provided for the chick room and an outlet 3| is provided for foul and damp air, said outlet 3| being equipped with a suitable ventilator 32. No air entering the chick rbom has come in contact with the heater H and thus its oxygen content is not impaired. This and the well ventilated and thoroughly warmed chick room provide much better living conditions with vminimum danger of loss from sickness. The air in the chamber A heated by the heater H would not ascend into the chamber A', were it not for the down-draught flues I3 and only the lower portion of the chick room would therefore be heated. Due to said flues I3 however, cold spots are provided in which the air descends causing ascent of warm air into the chamber A1', it being thus insured that thorough and uniform heating of the chick room be attained. The flues I3 need not extend entirely to the upper end of the chamber A' for the warm air will ascend somewhat past the openings I6. but without said flues the alr would not ascend to any appreciable' extent in the chamber A.

It will be seen from the foregoing that novel provision has been made for carrying out the object of the invention. Structural details which have been disclosed are for illustrative purposes only and within the scope of the invention as claimed, variations may be made.

Attention is invited to the fact that the thermal packing I5 against the outer wall I2, insulates all but restricted areas of said outer wall I2. The outer sides of the iiues I3 contact with these restricted uninsulated areas and are thus cooled thereby, causing descent of the air in the iiues to insure circulation of the warm air between the walls 6 and I4. By omitting the thermal insulation from the portions of the wall I2 contacting with the ues I3, I of course permit a slight loss of heat but the added efficiency iiowing from the warm air circulation, more than counteracts the loss.

1. A brooder comprising an inner and an outer casing having spaced bottoms and spaced side walls providing communicating horizontal and vertical chambers, closing means between the upper ends of said side walls, means for'heating the air in said horizontal chamber, thermal insulation covering the inner side of the outer casing side wall with the exception of restricted relatively long and narrow vertical areas thereof, and vertical air fiues contacting with said restricted uninsulated areas and having their upper and lower ends open to said vertical and horizontal chambers respectively, whereby said ilues'are cooled by contact with the uninsulated portions of the outsidewall, causing descent of air in said flues and thereby causing circulation of the warm air between the side walls of the inner and outer casings.

2. A brooder comprising an inner and an outer walls, closing means between the upper ends of said-side walls, means for heating the air between said spaced bottoms, an intermediate wall between said side walls and extending from the bottom of the outer casing to said closing means, the

upper and lower ends of said intermediate wall Y descent thereof to eiect circulation of the warm air between the intermediate wall and the side Wall of the inner casing.
